To all wh o r hithm lttydon/germ Be it known that I, J ULIUS A. SPENCER, a

Dwight, in the county of @Livingston and State of Illinois, have invented certain new and useful Improvements inBaling-Presses,

of which the following is a specification.

My invention relates to balingpresses such as are used for compressing and baling hay, staw, cotton, and the like to reduce the same to a form and size convenient for economical storage or shipment; and my inprovements relate more specifically to that class of baling-presses known as toggleresses, a type whereof is illustrated in my ormer patent, No. 7 08,269, granted September 2, 1902, upon which toabrtain extent my present invention bears the relation of an improvement.

The object of my invention is to improve baling-presses of this type, more'particularly in the direction of providing an improved feeding-in chamber, with novel mechanism for operating the extensible side thereof from the movement of the fulcrumed shorter arm of the plunger-actuating toggle, another object of the invention being to provide means,

' in combination with the feeding-in chamber and its actuating mechanism, whereby same parts on the line 3 3 of Fig. 2.

by the initial inward movement of-the compressingplunger (during which movement the extensible side of the feeding-in chamber is actuated) may be rendered easier on the team.

In the accompanying drawings, Figure 1 is a perspective elevational ,view of the portable press and plunger-operating mechanism. Fig. 2 is a horizontal sectional view through the feeding-in chamber on the line 2 2 of "Fig. 3. Fig. 3 is a cross -sectional view of the Fig. 4 is a top plan view, and Fig. 5 a longitudinal section on line 7 7 of Fig. 4, of the mechanism for increasing the leverage or arm of power through which the power is applied to the plunger at the beginning of its inward stroke. Fig. 6 is a detail of the mechanism for actuating the extensible side wall of the feeding-in chamber from the oscillating movement of a paratus, 20 may designate as an entirety t e baling or compression chamber, in rear of which is a feeding-in chamber 21, Fig. 2,

surmounted by a hopper 22 and having an extensible side 23, working in a laterally-extended housing 24 on one side of the feedingin chamber.

25 designates the compressin plunger, pivotally connected to the end 0 a plunger stem orrod 26, thislatter constituting one 'arm of a toggle, the,other arm whereof is composed of a pair of channel or other beams 27, pivotally connected by a pin 28 to the free end of the plunger-rod 26 and at their opposite ends rotatably mounted upon a transverse shaft 29, supported in and between a pair of rigid brackets 30, projecting rcarwardly of the main frame of the machine, as clearly shown in Fig. 1 A suitable depending frame 31 carries a'pair of grooved pulleys 32 and 33 and also supports the inner end of a hollow strut-bar 34, to the opposite or outer end of which is applied the mechanism through which the power of the team is applied to actuate thecompressing-plunger.

A chain 35 transmits the power of the team to the plunger on its inward or compressing movement. One end of this chain is connected, through a link 36, Figs. 4 and 5, with the free or outer end of the plunger 26, and said chain overlies and overrides a rigid guide secured to the divergent members 27 of the toggle-arm constituting an extension of the latter, said guide oscil ating with the short arm of the toggle about the shaft 29. This rigid guide is a trussed member, herein shown as comprising a pair of parallel bars 37, twisted through a right angle at one end and riveted to a plate 38, connecting the bars 27, said bars 37 overlying the pivoted shaft 29 and at their opposite ends extending to a position above the pulleys 32 and 33, said bars being' reinforced by truss-bars 39 and struts 40. The bars 37 are separated sufliciently to al- 5 low the vertical links of the chain to be guided therein, while the alternate links ride thereover. The chain 35 passes down around the pulley 33 and is connected, through a suitable link 4O and chain, to a traveler operat- 10 ing on a cam-block actuated by the sweep in the manner fully described in my aforesaid patent, No. 708,269. Another chain45, connected to a segment-block 46, fast on the shaft29, is connected, throu h a link 47 to an- 1 o latter has been retracte 65 limit, I provide means for retracting the From the foregoin and especially by ref- 5 compression-,chamberand compressed therein on the initial movement of the plunger the chain 35, by reason of passing over the inwardly-projecting end of the lower togglearm, obtains a leverage nearly equal to the length of said inward projection in effecting the initial inward movement of the plunger, thus lessening the severe strain upon the team resulting from the acute angle at which the toggle-arms stand at the beginning of thestraightening movement of the toggle.

Referring next to my improved mechanism for actuatingthe extensible side wall of the feeding-in chamber, and referring more particularly to Figs. 1, 2, and 3, 49 designates a pitman that passes loosely through a slot 50 in the rear wall of the casin 24, its inner end being connected to one 0 two airs of links 51 that are pivoted to lugs 52 on t e inner side of the side wall of the casm'g, the free ends of the up er and lower of said links 51 being connected by bars 53 whereby they are caused to move in unison. The pivoted ends of the I links 51 and bars 53 are pivotally connected to the meeting ends of two pairs of companionlinks 54, which latter are ivotally connected to lugs 55 on the outer, ace of the extensible side wall 23. This latter has formed on all four margins broad top, bottom, and end flanges 23 23 and 23, respectively, whereby it is guided in the casing 24, the end walls bein preferably provided with antifriction-rol ers 56. For reciprocating the pitman 49 sufliciently to effect, through the described mechanism, the inward and outward movements of the extensible side 23 the outer end of said pitman is connected by a lost-motion pin-and-slot joint, Fig. 1, to the upper end 0 a rocking frame 57, that is pivoted at its lower end on one of the axles, said frame at its rear end preferably being engaged, so as to rock the same, by the free end of an arm 58, connected to and forming an extension of" one of the arms 27 the engagement and disengagement of the arm 58 being ism shown in deta' in Fig. 6, wherein it will be seen that the vertical rear frame-bar 57 a of the oscillating frame has a rigid hook 59, projecting to one side thereof, beneath-which the arm 58 lies when raising the frame and actuating the pitman 49 on its inward movement, said bar also having beneath the rigid hook 59 a spring-latch 60, adapted to underlie the arm 58 and be engaged thereby to rock the frame in the op osite direction for the outward movement 0 the pitman 4.9. In

order to release the arm 58 from the actuating connection 57 of the itman 49 when the to or nearl to its effected at the pro er times by the mechanlatch 60, the same. comprising a pawl 61, pivoted to the frame-bar 57 a opposite the rigid hook 59 said pawl having a depending finger 61, normally lying behind an u standm finger 60 on the latch 60, and a l iorizonta finger 61", overl ing a rigid contact-bar 62, secured to one of the stationary frame members of the apparatus. From this it follows that when the rocking frame 57 is swung downwardly to a point where the finger 61 strikes and overrides the stationary bar 62 the latch 60 will be thereb retracted from beneath the arm 58, where y the continued swing of the latter will be without effect upon the actuating mechanism of the extenslble' side. The relation of the arts'is such that the extensible side 23 will e fully moved to its inner position by the time the plunger 25 has reached on its inward movement the rear end of the feeding-in chamber. The actuation of the extensible sideof the feeding-in chamber on itsinward or compressing movement takes place during the imtial part of the inward movement of the plunger just rior to the travel of the plunger through the eedinlgin chamber, this movement occurring wh' e the arms of the plunger-actuating toggle form a veryacute angle. The purpose of the forward extension of the toggle-arm on which the toggle-actuating chain acts during the initial part of the opening movement of the tog le 1s tosecure a mechanical advantage sufli'cient to overcome the resistance to the inward movement of the plunger represented by the actuation of the movable side of the feeding-in chamber. In balling-presses lacking a feeding-in chamber with a movable or compressing side the provision of the auxiliary leverage for starting the opening moverrentvof the toggle is unnecessary, since during the final compressing stage when the toggle is undergoing the last part of its straightening movement a greater amount of ower is required than is necessary to start t e inward movement of the plunger in the absence of the auxiliary leverage; but inpresses such as that shown herein, wherein the preliminary condensation of the hay or other material is eifected in a feeding-in chamber by means of a laterally-moving side or plunger in the latter, where the actuation of such lat-.

erally-moving side-or plunger is efiected'by and from the toggle-actuating means of the mainplunger, the provision of the auxiliary leverage is necessary to reduce the amount of power otherwise required to effectthe initial part of the opening movement of the toggle arms. r

It is evident that the particular forms and constructions herein shown and described mkilght be varied to some extent by those s led in the art without departing from the substantial rinciples of operationor sacriiicing any 0 the advantages attained by the invention.- Hence I do not limit the latter ICC to the particular details shown and described except to the extent indicated in specific claims.
